Enceladus looks as though it is half lit by sunlight in this view from NASA's Cassini spacecraft, but looks can be deceiving. The area on the right, where surface features can be made out, are actually illuminated by light reflected off of Saturn. A sliver of surface illuminated by direct sunlight is visible on the left.
